Application filed December 14, 1916. SerialNo. 137,022.

To all whom it may concern Be it known that we, HENRY F. PHILLIPS and HOMER V. DEAN, citizens of the United States, residin at Spokane, in the countypf Spokane and tate of \Vashi'ngton, have 1nvented certain new anduseful Improvements in Heaters for Water-Cooled Engines, of

which the following is a specification.

Our invention relates to new and useful attachments for internal combustion engmes and more particularly for internal combustion engines of moto vehicles having a water cooling system, the primary object of our invention being the provision of a heaterco6perating with the water cooling system so that the water contained in the water jacket of the engine and in the radiator may be kept warm when the engine isnot in use thereby doing away with the necessity of employing non-freezing solutions in the coolsystem during coldweather.

i'n J In this connection, our invention includes a heater adapted to be supported within the hood of the vehicle and awater holding receptacle from which ipes lead to the inlet and outlet pipes of t e water jacket of the engine. I

In this connection, a still further object of our invention consists in the provision of a novel .type of water receptacle ,which includes a relatively small tank surrounded by a heating coil which communicateswith the tank, the two being exposed to direct heat from the burner forming part of the heater.

Another object which we have in view is the provision of a heater for the coolingsystem of automobiles in which the water-for other cooling fluid may be heated either by a burner or electrically, as preferred.

With these and other ob ects in view, our

invention, will be more fully described, illustrated in the accompanying drawings, and then specifically pointed out in the claims which are attached to and form a part of this application.

In the'drawings:

Figure l is a side elevatio'n of a'conventional form of internal combustion engine in connection with the hood and radiator of a motor vehicle;

Fig. 2 is a front elevation of the structure shown in Fig. 1';

Fig. 3 is an elevation of the auxiliary ventional type and havingl heater forming part of our invention, the water receptacle and 0011 being shown in section; a

Fig. 4 is a plan view of the water-recep-v vision for electrically heating the water contained therein.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the san'ic reference characters.

In order to insure a clear and accurate understanding of our invention, we have illust ted it in connection with a motor vehicle having the usual dash 10 and hood 11 inclosing an internal combustionengine 12 of cona water jacket. Water is' supplied from t e usual radiator 13 to the water jacket through the inlet pipe 14. and passes back to the radiator through the usual outlet pipe 15.

Our invention, broadly speaking, includes a heater 16 which is preferabl supported within the hood 'by-a' bracket 1 secured to vis preferably in the form of a conventional lamp and lamp casing including the lamp proper 18 which should be of cylindrical wick type and the lamp casing 19 having the usual bulls eyes 20 through which the burner may be seen. A pipe 21 has one end tapped or otherwise fitted into the inlet pipe 14: adjacent its juncture with the water jacket of the engine and its other end passed in through the side of the lamp casing to communicate with a substantially cylindrical water holding receptacle 22 mounted directly above the burner so that it will be highly heated when the wick is lighted. The pipe 21 communicates with the lower portion of the container 22 at one side and a second erably somewhat rounded, as shown, and is bent to provide a helical heatin coil 24 extending downwardly and about tie container to a point adjacent its lower end. The free end of this pipe 23 is then bent upwardly and extended through the top of the lamp casing-Where it is connected toa pipe 25, the endof- Which is tapped or otherwise fitted intothe'outl'et' pipeltj of the water j acket adjacent its juncture with the inlet pipe of theradiator. 1

Obviously, when the above described device is installed, the container-22, pipe 21, pipe 23, heating coil-and pipe 25 will all become filled with water from the -Water cooling system of the engine. In cold weathencwhen there is danger of the water in thissystem freezing and so injuring the radiator or engine, when the engine is not I running, the wick of the .heater may belighted to heat the water contained in the receptacle 22 and heating coil 24:. The heating of this, Water will set up aslow circulation o he water through. both the waterjacket of the. engine and the radiator so that.

- j usted to give any desired'degree of heat and if ished the device may be utilized 'to in cold weather, even though an antifreez in a shorttirne all of the ,water in the cooling system will be warmed sufliciently to insure against freezing. .The burnermay be adkeep the engine warm to facilitate starting ing solution is employed in the cooling system so that thedevice need not be kept burns ing over long periods when the engine is not in. use.

If desired, the lamp or burner 18 may be omitted and the light casing alone employed with the containerand heating coil and the heat supplied by electricity. Such an ar: rangement is illustrated in Fig. fi'in'which' the parts are identical with those shown in Fig. 3 and are given the same-reference "characters. "As shown, however, a wire 26,

which willofi'er relatively high resistance 'to-the passage of an electric current, is run through a. portion of the pipe'2l, diametrically through the container 22, through'the pipe 23Land heating coil and out-through the side. of the pipe 25. The terminals of this f pipe are connected. to wires 27 and 28 whichlead to any suitable source of electrical energy, such asa battery '29, a manually operable switch 30, being preferably in-- eluded in one 'of these'wires. Obviousl-y',

withthis structure, closing of the switch will cause passage of a current through the high resistance Wire 26' and, consequent, heating of the water in the system. If desired, the form of heater illustrated in Fig.

3 may have a heating wire embodied in it in the manner shown in Fig. 5 and the eases-4 water may then be heated either. by means of" the burner or electrically, as desired, or as' conditions may direct.

'Although We have illustrated and described our invention in all its details of construction, it will of coursebe understood that We reserve the right to make any changes, within the scope of the appended claims, without [departing from the spirit of our invention. For instance, the entire burner orheater is. referably inclosed in a housing of fine 'wire-gauze in order to prevent likelihood'of "fire in case of leakage of gaso-lene about the motor. This housing of gauzeis shown in'section in Fig. 1 of the drawings at 31'. i

' Having thus described 1. An-apparatusof the class described comprisinga water tank, a pipe leading intothe lower end'of' the tank'through the side wall thereof and adapted to be connected into the feed end of an engine-water cooling system, a pipe leading from the top of the p tank and spaced laterally from said tankto form a circumferential heating chamber, the

pipe at the lower end of the coil being car'- ried upwardly onthe outside thereof and adapted to be connected into the outlet end of the. system, and means forheating the Water in the tank.

2. An apparatus of the classy described "comprising-a casing, a water tankdispos'ed within the casing in spaced relation thereto and having its bottom unobstructed, a pipe leadingthrough'the side of the casing and through the side of the tank'andintoflthe lowerend of saidtank and adapted'to .be, v

connected into the feed end of an-engine Water cooling'system,'a pipe leading from the top of the tankand bent to form a coil spaced laterally fromthe exterior of the tank to form an intermediateheating cham 'ber, the'coil terminating short of the bottom I 105' of the tank and the end thereof being extended upwardly on the outside of the coil tank and bent to form a coil surrounding the and through the top of the casing and adapted to be connected into the outlet end of the system, and a burner supported by the casing below the tank to direct'the heat against the bottom. ofthe tank and upw'ardly through the intermediate heating chamber.
